Baltimore started the day under muggy, gray skies and in the mid-70s, but the main event is still ahead. This afternoon, highs are expected to spike into the mid-90s, with brisk southwest winds and a late-day shot at thunderstorms. If you have outdoor plans, keep a Plan B handy, since the hottest and windiest stretch runs from midday into early evening, and any stronger storm could bring sudden gusts and lightning. It is a good idea to check updated forecasts before heading out.
Afternoon Heat And Storm Threat
According to the National Weather Service, Thursday highs are expected to reach around 95°F, with heat-index values climbing into the mid-90s in some parts of the city. The best chance for showers and thunderstorms runs from about 2 p.m. to 5 p.m. Storms will be scattered, but the strongest ones could pack damaging wind gusts and frequent lightning.
Afternoon Winds Pick Up
Southwest winds will build through the morning and into the afternoon, with sustained speeds generally in the single digits to low 20s and frequent gusts into the low 30s. That combination of heat and wind can make outdoor work feel even more punishing and can easily shove around unsecured patio furniture or decorations. Drivers should be ready for blustery crosswinds on exposed bridges and brief drops in visibility in any heavy downpours.
Bay, Tides And Boaters
The National Weather Service is also flagging marine hazards: Small Craft Advisories and Gale Warnings are posted for parts of the Chesapeake, and Coastal Flood Advisories are in effect for vulnerable low-lying spots along tidal rivers. Annapolis and Havre de Grace could see minor tidal flooding around this morning's high tide. If you park near the water or plan to get out on a boat, secure loose gear and consider holding off until winds settle down.
What To Do Today
Shift strenuous activities to early morning or evening, drink plenty of water, and take breaks in air-conditioned spaces when you can. For anyone who needs a cool place to ride out the heat, the Baltimore City Health Department recommends calling 311 to confirm cooling-center locations and hours on high-heat days. Keep a weather app close and move indoors at the first sign of lightning or a sudden burst of strong wind.
